When I refer to my "Twitter tools," I mean a Python command-line script that I use to post to Twitter from bash scripts, PHP programs, Node.js programs, etc. That Python script is little more than a wrapper around an abandoned open source library that broke when Twitter turned off API v1.0 -- twitter-oauth. The repository seems to have been emptied, too. Luckily, the library is still available in the Python Package Index: http://pypi.python.org/simple/twitter_oauth/
